The excessive consumption of fossil fuels and their derivatives, along with their extraction on the planet over the past 100 years, has caused serious problems that are already irreversible in terms of the environment, which implies that we have our days numbered. That is why it is necessary to carry out an energy transition where it is possible to abandon or reduce dependence on these fuels and other energy sources that seriously affect the environment. Taking the above into account, the study of new alternatives for the generation of clean energy from different points of view is becoming increasingly urgent, which is why energies such as tidal energy, wind energy and solar photovoltaic energy emerge as the main sources of renewable energy. At the same time, other forms of generating clean energy are being studied, which is where the world is studying the generation of green hydrogen as a source of energy and fuel to replace current sources. Research in the field of renewable energy, both in the country and at the Francisco José de Caldas District University, Technological Campus, is advancing rapidly, which is why this project aims to assemble a system to measure the energy efficiency in power generated by a fuel cell which is powered by green hydrogen obtained through an HHO cell and another HH-OO cell. These cells operate with solar energy, so the power generated by the panel will be used as a reference against the power generated by the fuel cell after the process is carried out. To this end, the system has a data acquisition card that is capable of taking measurements through voltage and current sensors to check the power production delivered by the panel and that 44111generated by the fuel cell, volumetric flow to check the production of hydrogen made by the HHO and HH-OO cells and thus be able to have a relationship between hydrogen production against power generated. This entire system has a visualization on an OLED screen while most of the variables will be monitored through the Matlab ThinkSpeak IOT platform, which allows us to have real-time visualizations while collecting data for later analysis. The research carried out in this thesis demonstrated the feasibility of generating DC voltage from green hydrogen produced by a solar panel. The efficiency of the system, although not optimal, opens the door to the implementation of this technology in renewable energy applications. It is recommended to continue researching the optimization of the system to improve efficiency and explore the application of this technology in different scenarios.
